CUHK-SYSU consists of 18,184 images, with 96,143 annotated bounding boxes and 8,432 identities. Two types of data sources are collected, exhibiting high degrees of diversities and variations, making it quite challenging. We follow [1]} to adopt the standard training / test split, with a training set of 5,532 identities and 11,206 images, and a test set of 2,900 query persons and 6,978 images. Unless otherwise stated, the results are reported by using the default gallery size of 100.
